finance cooperative business us
The AS handle NRUCFC is operated by National Rural Utilities Cooperative Finance Corporation.
What it's used for
- The address space carries corporate infrastructure for a nonprofit financial cooperative, with netnames
NRUCFC-1-IPandNRUCFCdirectly identifying the holder. - The inventory consists of 3 IPv4 prefixes totaling 768 addresses, observed against 2 routing neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
Notable
- Registrants largely align with the announcer, though the prefix 204.111.120.0/24 is registered to Shenandoah Cable Television LLC under the netname
SHENTEL, suggesting a specific asset or legacy allocation within the cooperative's portfolio. - The address inventory is minimal and finely subdivided into three /24 blocks, consistent with the segmented internal network of a large financial institution.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,847 prefixes, as published 2026-11-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
